Application of pile foundations with grillage in frost zone of heaving soils
Conclusions 1. The installation of piles and pile foundations leads to a reduction in the heaving of soil in the space around the pile, the smallest values of which are observed inside the pile group. 2. Frost heaving decreases and, consequently, the normal forces of frost heaving that act on the grillage diminish with decreasing distance between piles in the group. 3. During freezing, the layers of soil exhibit a complex mechanical trajectory. As the freezing zone approaches these layers, they are displaced downward, i.e., the process of compaction of the thawed soil occurs under the pressure induced by the frost heave, and upward displacement of the soil layers (heaving) is then observed after freezing. 4. As a result of the freeze-thaw cycle, the soil in the space around the pile is compacted under the frost-heave pressure. The proposed construction of precast-pile foundations with a grillage in the frost zone has demonstrated its own serviceability.
